i think it's great that UUC is offering another alternative for E36/46 cars. by offering the alcon kit, it doesn't mean that the wilwood kit is all of a sudden obsolete. it's just an alternative like rob stated above. different technology = different price points. with that said, i think i'm going to have to order this alcon kit!!

The #54 JP car ran about half the 2007 season on Wilwoods (and kicked major ass!). Spent the second half of the year testing the Alcon setup, and that's when it got the revised graphics.

Ash, big brake kits make all the difference. No need for driver talent.

...and no Rob, do not jump on my ass, it was a joke between Ashley and myself. Actually, I hate to admit it, the Alcon's look like a good kit. Never liked any of the past UUC BBKs or any other products since the orginal Rob Knob, wayyyyy back when.

Hey Rob random question - do you know if OEM ZHP wheels will clear the 4 piston wilwood caliper? I was recently thinking with the number of road trips i go on I should start carrying a spare, and I know my 17" spare doesn't make it. Was thinking of picking up a ZHP wheel.

Can't say exactly as I have not test-fitted the ZHP wheel. For either our Wilwood or Alcon kits, we've got the wheel fitment diagrams on our website. Simply print life-size (1:1 in printer settings), glue to a piece of cardboard, cut out the profile, and fit into the wheel. This will tell you exactly if there will be interference and will give you a good idea of how big a spacer (if any) you will need. You really only have to worry about the front, BMW rear rotor offset is so much greater that wheel fitment is almost never a problem.

First, you will notice that the initial UUC offerings are all 4-piston calipers and only modestly oversized rotors. This was done for very specific reasons, we're designing for racecar applications. In many racing classes, the rules limit upgraded brake calipers to no more than 4 pistons and no more than 5% over original diameter.

However, for those wishing larger, upgrading to the 345mm rotors for 4-piston kits is possible, as well as upgrading to the 380mm rotos for the 6-piston kits. A simple upgrade kit from UUC is available.

a) Steel brackets are "lifetime" whereas aluminum, due to accumulated fatigue, is supposed to be replaced at periodic intervals. Our heat treating process makes the steel much stronger than common aluminum brackets.
b) Stainless steel requires no plating, painting, or anodizing and therefore is a much more precise part. Common coating techniques for aluminum add variable thickness, which can affect caliper alignment.
c) Strength - steel is more resistant to deformation, resulting in better caliper alignment under stress and nonexistant flex, which means better pedal feel and pad wear characteristics.

Rotor costs:

UUC's basic floating rotor option uses genuine BMW Motorsport floating rotors made in Germany, which are available at a replacement cost for a complete rotor (which means it includes the hat) that is less than typical 2-piece rotors for the disk only.

For example, the BMW Motorsport floating rotors are approximately $215 each in the 325mm size. Complete rotors from other BBK companies run $495-$895 each. Disks alone will usually run $230-$350, and then you've got to re-assemble it with the hat.

All of that is just a brief overview. For more details (it's important to do thorough research for yourself!), please see:

Finally, realize that UUC now has an "official" development relationship with Alcon. For many of our applications, the calipers are custom-built to UUC's specifications for piston size and other details.

i think one very important piece of imformation that you left out is the difference in calipers used in the 2 kits...the Stasis kits use monobloc calipers which probably makes up a large portion of the price difference between the kits...

koni challenge ST and GS are they only 2 classes i can think of that have that rule...

Please review the application list I posted above, you will see that when specifically comparing apples to apples - meaning the Stasis 6-piston and UUC 6-piston for E46 M3, these are the exact same calipers. The only difference is we offer gray and red, and Alcon has made these in red for the very first time exclusively for UUC.

ah, so you are using monobloc calipers on your E46 M3 kits?

i reviewed the application list and there is no mention in your post or on your site that you are using monobloc calipers in any of your kits...and the only pictures that i've seen you post on forums or your site are of 2 piece calipers...

the only 2 classes that i know of that have that rule are GS and ST in koni challenge...bmwcca cr prepared class does not have this rule (rotor sizing is not specifically limited or maybe you can show me where the 5% over stock wording is?)...

Yes! The E46 M3 application will have the choice of 4-piston or 6-piston Monobloc.

They're not listed on the website yet because they are not available at this time... about another week. Magazine advertising has caught up with us, the 6-piston kits are listed in Roundel and Bimmer.

Okay... you quoted a sentence showing two parameters, and both are accurate. Some classes, as you listed, have both and some have one. Your request for confirmation was obfuscated by insufficient clarity.

ah...when i see a statement or rule with "and" in it, i take that to mean that all parameters must be true (not just one or more)...

maybe your statement should have read: In many racing classes, the rules limit upgraded brake calipers to no more than 4 pistons and/or no more than 5% over original diameter. - that would have widened the scope to more than 2 race classes

and since we're being picky, maybe the wording should have been clarified even further since i've never seen calipers limited to 5% over the original diameter, only brake rotors. maybe this wording would have been better- In many racing classes, the rules limit upgraded brake calipers to no more than 4 pistons and/or rotors to be no more than 5% over original diameter.

You, sir, are a true litterateur, the epitome of a wordslinger savant. I salute your superior syntactical dexterity.
